I believe the answer is:

spiracle

I'm a little stuck... Click here to teach me more about this clue!

'vent for breathing' is the definition.
'spiracle' can be an answer for 'vent' (thesaurus). I'm not certain of the 'for breathing' bit.

'second design of replica' is the wordplay.
'second' becomes 's' (common abbreviation).
'design of' is an anagram indicator (I've seen this in other clues).
'replica' is an anagram of 'piracle'.
's'+'piracle'='SPIRACLE'

Can you help me to learn more?

(Other definitions for spiracle that I've seen before include "Breathing space" , "Whale's blow-hole" , "passage through rock" , "Opening" .)

I've seen this clue in The Telegraph.
